Paper Abstract

The results of measurements of an electron density in a microwave plasma filament in dense gas (argon) are reported. The electron density has been determined on the basis of Stark broadening of lines detected in the absorption spectrum. A high-resolution spectrometer incorporating GaAlAs diode laser operating at 870 nm has been used to measure Stark broadening and shifts of the argon line. The electron density in the filament was found to increase from the initial level of 10 exp 12/cu cm to value n sub e greater than 10 exp 16/cu cm. The dependencies of the electron density on gas pressure and microwave power density are presented.
